2005-2015 JDM Toyota Tacoma 1GR-FE 4.0L Engine

The 2005-2015 JDM Toyota 1GR-FE 4.0L V6 engine is a popular, highly durable replacement engine option for second-generation Toyota Tacomas. Because the Tacoma was manufactured for the North American market rather than Japan, "JDM" versions of this engine are actually sourced from Japanese-market donor vehicles that shared the same powerplant—such as the Toyota Land Cruiser Prado, Hilux Surf, or FJ Cruiser. These imported engines are favored by truck owners because vehicles in Japan generally accumulate low mileage before being decommissioned.

Core Specifications

• Engine Displacement: 4.0 Liters (3,956 cc)
• Configuration: 60-degree V6, Aluminum block with iron cylinder liners
• Valvetrain: DOHC, 24-Valves with Single VVT-i (for 2005–2015 Tacoma applications)
• Output: 236 horsepower and 266 lb-ft of torque

Key Buying & Swap Considerations

• Long Block vs. Complete Assembly: Most JDM engine imports are sold as "long blocks" (the cylinder head and engine block). You will typically need to swap over your Tacoma’s original intake manifold, exhaust manifolds, oil pan, sensors, alternator, and wiring harness to ensure full compatibility with your truck's ECU
• Single VVT-i vs. Dual VVT-i: Second-generation Tacomas (2005–2015) exclusively used the Gen 1 Single VVT-i version of the 1GR-FE. Ensure you do not accidentally purchase a newer Dual VVT-i version (found in 2010+ 4Runners), as it will not plug into your Tacoma's electronics or factory harness.
• Head Gasket Reassurance: Early versions (2003–2005) of the 1GR-FE were known for occasional head gasket failures around cylinder number six. Toyota redesigned the gasket for 2006+ models, resolving the issue. Buying a replacement engine from the later end of the 2005–2015 spectrum offers maximum reliability.
• Legendary Longevity: When properly maintained with regular oil changes, a healthy 1GR-FE engine routinely exceeds 250,000 to 300,000 miles without needing a rebuild
